Vandiyan doesn't mean noise as in white noise, as in what you seen on screen, but means hearing white noise...
I have no idea why you should be though. I can hear high pitched noise though coming from my TV when displaying black, and at 60hz, but thats a big CRT TV...
By any chance have you got a microphone active on your monitor that maybe came with it built in, which may be interfering with signals?
If you have, open up Volume Controls in the task bar, and mute the microphone. Any difference?
It might also just be normal though in some circumstances depending on what you have.
When displaying all White you see, I think all the protons, etc in the monitor hitting the conductive part so you can see them are positive, and so might buzz slightly, I don't know.
It might just be you have super human hearing
If its bothering you that much, it might be best to have it checked out by where you bought it, or to try replacing it
